With externally applied magnetic fields, we will concentrate in vivo diamagnetic Bismuth particles or unipolar magnetic particles as a confined locus, then push the locus to move to a tumor, shape it to the tumor, then use near IR to heat the particles so to destroy the tumor by thermal ablation or hyperthermia treatment. We will then cause the locus to move to other tumors, and repeat the process, so to destroy all tumors and cure the cancer.
